It means the TABLES package is defined, but not actually installed. Either you installed only the source, the wrong binaries, built from source but it didn't put the binaries in the right place, or the extern.pkg file simply defines the package so it shows up in the menu but you didn't actually install TABLES in any way yourself. There are more obscure reasons for the error but check the above first and make sure TABLES is installed.

I just did a google search and found it. It's a file permissions thing. I'll contact my system admin.Here's the link. It's on page 23.http://webcache.googleusercontent.com/search?q=cache:25smoHpqlIsJ:www.stsci.edu/ftp/documents/stsdas-docs/UserGuide_chap/08_trouble.ps+%22ERROR:+Cannot+open+connected+subprocess+%28./x_ttools.e%29%22&cd=1&hl=en&ct=clnk&gl=us"File Attributes
System administrators need to make sure that file protections are set
correctly on all files used by IRAF and STSDAS. For example, if users do
not have execute permission for the task executables, they will see a
message like:
ERROR: Cannot open connected subprocess
(stsdasbin$x_ttools.e)
System managers also have to make sure that read-write-execute
permissions are set correctly on disks and directories used by IRAF. For
example, some tasks write temporary files to the disk and directory pointed
to by the tmp$ variable. If that disk or directory has its permissions set
wrong, you might see an error message like the following:
ERROR on line 51: cannot open ‘tmp$celco4944c.com’ for writ-
ing
celco ()
celco ()
or
ERROR (741, "Cannot open file (tempdisk:[iraftmp]sgk9554a")
Permission problems can sometimes manifest themselves in strange
ways, for example, IRAF networking can fail when system-wide default
login files have incorrect permissions. Users who encounter problems with
incorrect permissions on temporary or scratch disks can work around the
problem by setting up a temp subdirectory in their own home directory
and redefining their environment variables, for example: reset
tmp=home$temp/
If your tasks cannot open files, it is also possible that the files have been
inadvertently moved or deleted. Try moving to the directory and listing the
files to see if they really exist. If you find that you’re gettingpar files left
in strange directories where you didn’t expect them to be, then you’re
probably not starting IRAF from the correct directory. Always start the CL
from within your IRAF home directory. (Some of the extraneous files you
might get will be things like uparmimsimhism.par or perhaps
uparmsymlprint.par)."Regards,
Eric

That's one of the "more obscure reasons" I mentioned, ....make sure the package is actually installed first.

Hi fitz,Thanks for the reply.I installed TABLES yesterday before I got the error. And I checked my extern.pkg. It might be that I installed the wrong binary.I hope the file attributes thing works. If not I'll compile it from source.Thanks,
Eric

Problem solved. It was because the installation instructions I
followed for tables told me to place the binary files inside a folder
called bin.linux, whereas I should have placed them inside a folder
called bin.redhat, because my system architecture (shown by typing
"show arch" at the iraf command prompt) is redhat. I placed the binary
files inside the correct folder and now it works.Thanks for the help.
